Hi all, I am experiencing some odd direction changes on a home-brew CNC machine that I have on loan. The machine was apparently purchased off ebay, and all the settings I dug out from data sheets for the driver chips and motors.
X and Y are working well, but Z (which has a similarly spec'ed but different motor from the other two) decides to change direction at random. The basic behavior is that when you push the jog button in a certain direction you don't know which direction it will go. It will maintain it's course in that direction, but when releasing the button and pressing it again, it will again choose a random direction. Thus the problem it is very easy to reproduce. I am interested to hear what you think this problem may be caused by? I have yet to pull out the oscilloscope, but being a relative newcomer I wanted to ask for advise on how best to debug this problem. I should add that I did have this CNC set up briefly on Mach3, and encountered the same issue.
